How do you do matrix operation in casio fx991ms?

Answer 1

To do matrix multiplication in calculator Casio fx-991MS follow the steps below:-

1] Enter in the matrix mod:-

press MODE 3 times then press 2.

2] To enter the matrix:-

press SHIFT and then 4.

press 1 to select Dim. to enter the matrix.

Suppose u hv to multiply the matri A with matrix B

then seletect A by pressing 1

chose dimension for matrix A

let m=2

so press 2 then '='

again

let n=2

so press 2 then '='

Now, enter the values in matrix

MatA11, MatA12, MatA21,MatA22

every time enter the value and then ' =' to enter another values..

remember values get stored in the sequence of row mean 11,21,21,22

now u feel all the values of Matrix A

now to enter value of matrix B

press SHIFT and again 4.

seect Dim by pressing 1.

this time chose Mat B

and follow the steps same as u use to feel values in matrix A.

after entering the values.

u stored matrix A and B.

to multiply matrix A and matrix B

press 1(select Mat A) then press Multiply operator(*/cross).

again press Shift then 4 then press 3 and nw selec/press 2(select Mat B)

then press '='

4] you will get the another matrix Ans

But the values are in the sequence of row

to see next vaues in that matrix press '>' side of REPLAY button.
